Different Optics for Different Rifles

As battle rifles, battle carbines, and tactical rifles solve different (though occasionally overlapping) problems, their optics will be somewhat specialized.

Battle Rifle Optics

Battle rifle optics include for example Burris3-9x Fullfield II. According to Boston T Party, "Optics must be very rugged and versatile. Rugged because a .308MBR has hefty recoil and sees hard use. Versatile because the battle rifle will be employed for everything from CQB to precision work. Hence, it must have a quickly acquired point of aim, as well as range findingstadia lines and a BDC. The scope mount should be see-through in order to have immediate use of the iron sights. While I have a lot of experience with the I.O.R. M2 4x units, the Burris Fullfield II ballistic-Plex scopes have now gained my favor as very affordable and rugged optics for battle rifles."[2]

Battle Carbine Optics

Battle carbine optics include for example the ACOG. According to Boston, "Optics must be rugged, lightweight, and offer very fast target acquisition for CQB. A circle, dot, or triangle point of aim is the norm, and it should be illuminated at all times day or night (e.g., ACOG "BAC" system with tritium). Distance stadia lines are nice (e.g., ACOG), but not absolutely necessary (e.g., the AUG's 5MOA 'doughnut of death"). As in battle rifles, the scope mount should also be see-through if possible."[3]
